Ivan is a semi-strong van from B.J. Sweeney's Big Top Circus.
Ivan appears to b an orange VW bus with a white bumper, a red nose, red pinstripes, a grey front, and blonde hair. He wears a leopard jungle vest. Ivan speaks with a Russian accent.
Ivan is the successor for Hectro the Strong Van. He inherited Hectro's power shake recipe after Hectro retired but it later went missing. Without the power shake Ivan didn't have enough energy to lift the 1 ton weight. Putt-putt later finds Hectro's power shake recipe and makes a power shake for Ivan. Ivan then drinks the shake giving him the energy he needed to feel strong again.
